The Japanese yen weakened to 162.27 per U.S. dollar in early Asian trading on Tuesday, reaching its lowest level against the U.S. dollar since 1986. This depreciation prompted Japanese government officials to issue warnings about potential intervention in response to currency movements.

Japan Finance Minister Satsuki Katayama stated on Tuesday that the government was prepared to take appropriate action against excessive currency moves. Katayama added, "That includes taking decisive action, as confirmed between Japan and the U.S." Japan Chief Cabinet Secretary Minoru Kihara also stated at a press conference on Tuesday that the Japanese government plans to build an economy less susceptible to foreign-exchange volatility. Kihara indicated that the government remains prepared to intervene in currency markets if deemed necessary, though he declined to comment on the yen's current level.

Julia Wang, Nomura North Asia chief investment officer, noted that Japan could intervene in the foreign exchange market following the yen's slide to a new multi-decade low. "This is a cycle high; it's a new cycle high," Wang said. "It probably is a sensitive level, it will re-ignite some of the anxiety around currency weakness domestically." Wang also explained that intervention should not depend on a specific level. "Intervention shouldn't be dependent on a certain level," she said. "It depends on the nature of the currency move, the nature of dollar-yen..."

Wang expects any market intervention to have a short-lived impact on broader markets. The yen's broader outlook remains weak, according to Wang, because wide interest-rate and real-yield differentials between Japan and the U.S. continue to favor carry trades. "I don't think it will be a material factor that derails the market," she said.

The Bank of Japan recently raised its benchmark interest rate to 1%, which is its highest level in more than three decades and the highest borrowing costs since 1995. This quarter-point increase marked the Bank of Japan's first rate hike since December, when it lifted rates to 0.75%. Japan has been addressing rising inflationary pressures, partly due to higher energy prices during the Iran conflict.

Why It Matters

The Japanese yen's depreciation to a 38-year low marks a low point for the currency since 1986. Government officials' warnings about intervention reflect a strategy to stabilize the currency. The Bank of Japan's recent interest rate hikes also represent an attempt to counter inflationary pressures, but wide interest rate differentials with the United States continue to put pressure on the currency.
